IT-REFERENCE 16 E OWNER’S MANUAL
6
Testing the IT-Reference 16 E’s GFCI once a
year is recommended. Simply press the button
marked “GFI TEST.” If the GFCI is functioning
properly, this will cause the main circuit
breaker/power switch to trip and cut off power.
After verifying the GFCI’s proper operation,
simply restore power by switching the Circuit
Breaker/Power Switch to the “1” position.
AC Transient Voltage Surge
Suppression and Extreme
Voltage Shutdown
Extreme Voltage Shutdown Indicator:
This LED is normally off. It monitors AC wiring
faults – for example, accidental connection
to an open neutral (in some countries) could
put well over 300 VAC RMS onto the mains
outlet. When the Series Multi-Stage Protection
Plus (SMP+) circuit senses voltages that are
so high that operation would be impossible,
it shuts the power down before damage can
occur. Upon initially applying power to these
units, the Extreme Voltage indicator LED will
light if the input voltage is above the extreme
voltage cutoff, and power will not be applied
to the unit’s outlets. If the unit has been
operating with an acceptable input voltage
and subsequently that voltage exceeds 270
VAC, it will shut off power to the outlet and the
Extreme Voltage LED will light.
Protection OK Indicator:
Although the Furman SMP circuit assures
virtually maintenance free protection from
transient voltage spikes and surges, nature
has a way of occasionally creating electrical
forces that are beyond the capabilities of any
